When I was in the sixth grade, one day my teacher asked our class to think about the question “What does ‘doing the right thing’ mean to you?” over the weekend. We could talk to our parents or anyone else we thought might have a good answer.  1  Monday, we were to hand in an essay（论文） on it, and be prepared to live up to our  2 .        
The entire weekend, I was trying to  3  something that would impress my teacher and be easy to live by. I talked to my parents, called my grandmother and asked my neighbor. Everyone had good answers, but I didn’t feel like I could live up to them.
On Sunday afternoon, my parents said they were going to my Aunt Cindy’s house. That usually 4  that I would have to entertain my four-year-old cousin Andrea  5  my parents visited. I found a Disney movie for Andrea, and then I sat down and started to write my essay. It was due（到期的）the next morning and this was my last  6  .
Soon I felt a pair of eyes on me. It was Andrea.  “What are you doing?” Andrea asked. “I have to write an essay about what ‘doing the right thing’ means to me.” I answered. Andrea laughed. Could this smart four-year-old 7 know the answer?  “That’s easy,” she said. “Doing the right thing means being nice to your family and friends. Never lie. Eat lots of fruits and vegetables. Take a bath when you’re 8 . And never put rocks in your mouth.”
I stared with great  9  at my little cousin. Then I jumped up and gave her the biggest hug. Not only had Andrea answered a very tough question for me, but I could easily live by  10  of her answers. All I had to do was to be nice, not to lie, to keep myself clean and healthy, and never put rocks in my mouth. So when I wrote my essay, I  11  the story about Andrea and how she had answered my question.
Two weeks later, my teacher returned everyone’s essays. I  12  an A+ along with a little note my teacher had written at the top: “Always do the right thing and give Andrea an A+, too!”

My tears run down when I talk to my parents on the phone. What are they doing when I 41 them?
Dad works from 7a.m to 9p.m. Mum does all the 42 . She also has to work in the vineyard (葡萄园). But I can’t do 43 for them. Every day she got up earlier than Dad. When I 44 call her at 7:30 in the evening, she is still working and 45 supper. How hard it is for a daughter to stop the 46 in heart! And even harder to keep back the tears. 47 only thing I can do is to promise her that I’ll study hard in the university. I also 48 her to take care of herself and dad. I can not live 49 them.
Mum says the happiest time for dad and 50 is when my sister and I return home. We play 51 in the room, watch TV or do anything we like, with dad 52 mum cooking together in the kitchen. It is 53 the happiest time for me. I’ve never thought my holidays at home could be so 54 . I wanted to do more housework because mum really needs more rest.
Love, sometimes, doesn’t need too many 55 . We may be too shy to say the warm word out. Then give them a call and tell them you miss them.

Thousands of years ago, people didn’t know that the Earth moved. They thought the sun really did move across the sky. The Greek god Helios was said to drive the sun around the sky with his chariot（战车）. But now, these ideas have all changed. Nowadays, it is the sun that drives our “chariot” around the sky.
So what does all this mean? Well, quite simply, there is now a plane （or “chariot”） that is powered by the sun. It has special parts in its wings. These parts absorb power from the sun. They absorb so much power that they can carry on flying at night. In the Greek myths（希腊神话）, Helios had to take a break at night. It seems we’re finally even more efficient than the gods themselves.
This plane is called Solar Impulse （“太阳驱动”号）. It will fly across the US in May. This is very important for the future of the world.
So why is solar energy so good for us? Well, other kinds of energy cause a few problems. If you live in China, you’ve probably noticed the pollution. This is caused by burning coal or gas to make energy. The heat and chemicals（化学制品）from this make things work. But if we use the heat from the sun, we don’t have to burn anything, and there’s no pollution.
Solar energy is not all there yet. It needs to be improved. But the best thing about it is that, unlike coal and gas, it doesn’t run out. Solar Impulse could keep flying forever. Well, actually, the sun will run out too, one day, but not for another 5 billion years. That’s a pretty long flight.
